The sawfly lays its eggs in the lower part of the shrub. The false caterpillars eat holes in the leaf, they start at the bottom of the bush and in a short time the many caterpillars cover the entire shrub. They eat the mesophyll; they leave the leaf veins intact.<\/p>\n

The Common goose<\/wbr>berry sawfly has two generations per year; three during hot summers. The larvae overwinter in a cocoon underground. In the spring, the larvae pupate and the sawflies emerge. The female sawfly lays a whole string of eggs (50 to 100) on the underside of the leaf. After about a week and a half, the caterpillars hatch and feast on the leaves.<\/p>\n

Gooseberries are the most susceptible to the Common goose<\/wbr>berry sawfly, followed by red and white currants<\/a>. On black currants, the sawflies are hardly spotted.<\/p>\n

Similar to the Common goose<\/wbr>berry sawfly are the Pale-spotted goose<\/wbr>berry sawfly (Nematus leucotrochus)<\/em> and the Small goose<\/wbr>berry sawfly (Pristiphora appendiculata)<\/em>; however, these sawflies have a pronounced preference for gooseberries. Unlike the Common goose<\/wbr>berry sawfly, the Pale-spotted goose<\/wbr>berry sawfly has a single brood. Adults of the latter appear in early May and larvae in May and June. The Small goose<\/wbr>berry sawfly can produce up to four generations of larvae per season – the first generation appears at the end of April.[\/vc_column_text][\/vc_column][\/vc_row][vc_row equal_height=”yes”][vc_column width=”1\/3″ css=”.vc_custom_1532102781238{background-color: #ffffff !important;}”][vc_custom_heading text=”Where to find” font_container=”tag:h4|text_align:center|color:%23ffffff” google_fonts=”font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal” css=”.vc_custom_1532165393091{background-color: #536895 !important;}”][vc_column_text el_id=”entrytxt” el_class=”entrytxt” css=”.vc_custom_1680967483599{padding-left: 12px !important;}”]<\/p>\n
